Emilio Cobos Álvarez 4c1252347e Bug 1533783 - Avoid crashing when calling insertRule("@import ...") on a detached sheet. r=heycam
This should unblock the fuzzers for now, though it's not the ideal solution.

It's the only reasonably easy solution to unblock them though, I think.

We should probably always keep track of the document a stylesheet was associated
with. We'll need that for constructible stylesheets anyway.

That requires some though on how to get the cycle-collection and such right,
though, and I wouldn't be able to write or land that ASAP.
